Hello. Recently, I haven't been able to access my PS4. When I turn it on, it checks the system storage (which takes a while), then it says 'Cannot start the PS4. Connect the DUALSHOCK 4 using the USB cable and then press the PS button. After this it tells me to 'Connect a USB storage device that contains an update file for reinstallation for version 4.07 or later. You can download the update file for reinstallation from playstation.com.' After this (even though I have followed these steps; downloading 4.07 onto a USB), it tells me that it 'Cannot find an update file for version 4.07 or later. You can download the update file from playstation.com'.
I have followed all of the steps online and also, on my PS4. I have been on safe mode and tried everything; on youtube; taken my HDD out and even bought a new USB. I have tried everything and still aren't having any luck. I'm not sure whether this means anything but I believe it is the error code '(SU-30649-2)' My PS4 username is 'Eroom02'. I would sincerely appreciate if you would let me know what is wrong or fix it. Thankyou for your time and your work!
